window net update

[RACER1530]

a little off topic, but any word on secondary breaking system ?

Wtf. I just got mine. Thats a stupid rule anyway , how come you dont have to replace arm restraints?

[Dave Steltz]

For full-bodied cars running 7.50 (*4.50) to 9.99 (*6.39) or if vehicle runs 135 mph or faster a ribbon-type or SFI 27.1 mesh-type window net is mandatory unless otherwise specified by class requirements.

SFI 27.1 window net, when required, must be updated at two-year intervals from the date of manufacture.


So I'm still a little confused I guess...This says that for 7.49 to 9.99, I have to have a window net, a ribbon type OR a SFI 27.1 mesh-type net...and if a SFI 27.1 net is required, it must be certed every 2 years...

What am I missing ???? Is it saying that the ribbon type doesnt have to be SFI 27. and the mesh type does ?

Dazed and confused by the constant bombardment of NHRA rules makers...

Dave,
Looks to me that they snuck in a revision after everyone (including myself) scrambled to meet the new rule and purchased a new net and set up. Not that cheap or simple in some cases. My original 27.1 was custom made to fit my car. So now I modifed all the brackets which took me hours to do so I can just replace a standard off the shelf item every two years. All for not!!! Thanks again NHRA!!!!
I would love to sit in the board room one time and listen to how these decions are made. If I am not mistaken the same deal went down years ago with the diapers.

The last time this came up a few years back the rule was unclear and I did the same and replaced it. Only to find out in tech that it was not necessary. Custom made one also. Thanks again NHRA.
